운동의 필요성을 절감하면서도 여러 가지 이유로 마땅한 운동을 찾지 못하고 있는 현대인들, 이런 사람들에게 줄넘기를 권하고 싶다. 특별한 공간이나 기구 없이 줄넘기 한 개만 있으면 남녀노소 누구나 할 수 있는 줄넘기는 기초체력 보강은 물론 심장병 · 비만 예방 등에 놀라운 효과가 있다고 한다. 이처럼 특별한 기술을 요하지도 않고 온 가족이 함께 즐길 수 있는 줄넘기 운동 보급을 위한 ‘심장병 예방 생활체육줄넘기 축제’가 국민생활체육협의회와 한국심장재단에 의해 올해로 세 번째로 열렸다. 이 행사의 이모저모를 살펴보면서, 또 줄넘기가 구체적으로 어떤 효과가 있는지 알아보았다.

Jump-rope is a simple and effective exercise, but its intensive exercise load and monotonous pattern make it difficult to perform consistent workout. On the other hand, jumping rope accompanies large amount of kinetic energy which can be converted into electrical energy. In this study, we designed and implemented a self-powered jump-rope which can support the low-power embedded Bluetooth system inside it. The embedded system wirelessly transmits the acceleration data measured during jumping-rope exercise to a smartphone. We also developed a smartphone app which can count the number of jumps and provide real-time feedback with sound and animated graphic effects in a game context. Pilot test using the prototype smart jump-rope verified that it can be useful to motivation for the jump-rope exercise and make the exercise more effective by providing users with precise information about their exercise. We expect that the developed self-powered jump-rope will change the exercise from an intensive physical activity into electricity-generating fun experience combined with smartphone game, which maximize the benefit of the consistent jump-rope exercise.

줄넘기는 오래전부터 건강운동과 미용체조의 일환으로 일반에게 널리 사용되고 있다. 최근에는 줄넘기의 손잡이와 줄에 다양한 기능을 부가하여 손잡이에 줄을 넘은 횟수를 카운트하여 표시해 주거나, 스피커를 구비하여 음성출력을 부가하거나, 줄의 재질 및 형태도 다양화하여 줄의 무게를 조절할 수 있는 기능을 부가하고 있다. 본 논문에서는 운동하는 사람의 정보를 기반으로 적절한 운동량을 조절하도록 사용자의 줄넘기 횟수 및 운동 시간 등을 스마트폰으로 전송할 수 있는 스마트 줄넘기 모듈을 블루투스(bluetooth) 기반으로 개발하고자 한다.

The purpose of this study is to identify the effect of rope-jumping to music with weight loading on middle school girls' blood lipid and growth hormone. Toward this end, the study targeted 24 middle school girls at Y Girls' Middle School in Yangsan, Gyeongnam, who have no health problems or exercise experience, after sufficiently explaining to them the study's purpose. The selected students were categorized into a music rope-jumping group (8), a music rope-jumping group with weight loading (8), and a control group (8). In a comparison of blood lipid within the exercise groups showed that the music rope-jumping groups' measures changed significantly by demonstrating increases or decreases in RBC, T-C, TG, HDL-C and LDL-C (p<0.05). The music rope-jumping group with weight loading showed significant differences in WBC, RBC, glucose, T-C, TG, HDL-C and LDL-C by demonstrating increases of decreases (p<0.05). A comparison between the exercise groups revealed that the music rope-jumping group showed significant increases in growth hormone (p<0.05). The music rope-jumping group with weight loading also showed significant increases in growth hormone (p<0.05). The study's results identified music jump-roping with weight loading to effect students' blood lipids and growth hormone.

줄넘기는 줄을 돌리는 손동작과 뛰어오르는 동작이 결합된 운동으로 정확한 카운트를 위해서는 두 동작을 함께 고려해야 한다. 이전의 연구들에서는 단순 반복적인 운동인 윗몸일으키기, 팔굽혀펴기, 아령 운동과 함께 치부하여 하나의 동작만을 체크하여 카운트 하였다. 이것은 실제 줄넘기 동작과는 차이가 있으며 두 동작 중 하나의 동작만을 하고 있다면 확인해내지 못하는 문제가 있다. 본 논문에서는 6축 가속도 자이로 센서를 이용하여 두 동작을 모두 확인하고 카운트하는 방법을 제안한다. 가속도 센서를 이용하여 뛰어오르는 동작을 확인하며 자이로 센서를 이용하여 손동작을 확인한다. 이때 확인되는 값의 파형을 이용하여 줄넘기 횟수를 카운트하게 된다. 제안하는 방법은 실제 실험을 통하여 카운트 방법의 성능을 확인할 수 있다.

In an attempt to observe the effects obtained by the regular physical training, nine soldiers performed regularly the rope-skipping for nine weeks. All subjects were healthy and did not experience any special military training Programs. During the course of the training, their cardiopulmonary functions were measured in the resting and the Post-exercise recovery periods, and the values were compared with ones of the pre-trained. The test exercises loaded to the subjects were rope-skipping and step-rising & falling. The results obtained were as follows: 1) By the training, heart rates decreased very significantly in the resting and post-exercise recovery periods. And the effects began to bring out at the early stage, about the 7th day. 2) As the duration of the training increased, the systolic blood pressures decreased meaningfully in the resting and recovery periods. 3) Only in the early recovery phase after the exercise of the rope·skipping, the respiration rates decreased significantly by the training. 4) The lighter the intensity of the test exercise loaded was, the more prominent the effect of the physical training on the cardiopulmonary functions was. The above results suggest that the 9 week training of the rope-skipping would bring about the enhancement of the cardiopulmonary functions.

The purpose of this study was to determined the effects of music rope skipping exercise on dynamic, static balance, and body compositions in intellectual disabilities men. The subjects were twenty men who were randomly devide into two groups (exercise group, n=10, and non-exercise group, n=10). The subjects done the music rope skipping exercise three times per week for 60 minutes each time for 12 weeks. As a results, there were significantly improved the dynamic and static balance abilities after music rope skipping exercise for 12 weeks. Also, There were significant differences in body weight and percent of body fat after the exercise program. Accordingly, It was effective improved on body balance abilities and body compositions after music rope skipping for 12 weeks in intellectual disabilities men.

The aim of this study was to provide basic programs for addressing the growing problem of adolescent obesity by considering the effects of a music rope skipping-based exercise program to increase the student athletic ability on obesity, adiponectin and abdominal fat. The subjects were 23 male middle school students, 14-year-old to 16 years old, with a BMI of more than $25kg/m^2$ (experimental group 11, control group 12), who lack basic physical fitness physical health related fitness. The subjects received a 12 weeks music rope skipping exercise program. The program was carried out before and after the 12 weeks group music rope skipping exercise program. The adiponectin and abdominal fat measurements were compared with the degree of improvement. The BMI and adiponectin levels decreased significantly after the program. In addition, the visceral fat, subcutaneous adipose fat and total abdominal fat in summer decreased significantly.

Jump rope has two motions. It starts as hand motion and ends as jump motion. Therefore, two motions should be considered together to detect rotations accurately. But previous researches only consider one of the two motions as in push-up, sit-up, lift dumbbells etc, which results in inaccurate detection of rotations. In this paper, detection of rotation in jump rope using two motions through 6-axis accelerometer gyro sensor is proposed. Jump motion is detected using accelerometer sensor and hand motion is detected using gyro sensor. Also start point and end point of jump rope is detected using magnitude and standard deviation of accelerometer and gyro sensor values. The count of rotation is detected using y-axis of gyro sensor value. Y-axis of gyro sensor value indicate hand motion of jump rope motion. The usefulness of the proposed method is confirmed through experimental results.
